压力容器用大幅面爆炸焊接不锈钢复合板缺陷形成机理

摘要

It is appeared some strip defects ,which 80~200 mm width and 400~600 mm,maximum 2000 mm length,located near the diagonal line ,1000 ~2000 mm left corner, in the interface of metal clad plates when the large acreage metal clad , especially stainless steel clad plates which the width of more than 2600 mm and 10000 mm long was explosive welded .Such defects was effected the overall quality of the clad plate and increased the product manufacturing costs as well as limited the larger acreage metal clad plate products of explosive welding .Based on the analysis of interfacial space exhaust path ,this arti-cle is reasonable explanation the defects appeared in explosive welding of large acreage stainless steel clad plates,so as to take effective methods to reduce and eliminate such defects .%在爆炸焊接宽2600 mm、长10000 mm以上的大幅面金属复合板中，常常发现在对角线附近，离开板角1000～2000 mm处，出现条状不结合缺陷，缺陷宽度一般在80～200 mm，长度为400～600 mm，最大长度可达2000 mm。这种缺陷的出现，严重影响了复合板的整体质量，增加了产品制造成本，限制了爆炸焊接更大面积的金属复合板产品。通过分析界面空间的排气路径，合理地解释了爆炸焊接大幅面金属复合板，特别是不锈钢复合板时，这种缺陷的形成机理，从而采取有效方法和措施来减小和消除这类缺陷。
